hi everyone!

this is my very first coding experiment - so please forgive if it does not look as pro as it could
----------------------
size(800,500);
background(0);

//grid
stroke(50);
line(0, height/2, width, height/2);
line(width/2, 0, width/2, height);

stroke(255);

float n=0.1;

//parameter r0 can be adjusted towards maxr. maxr can be adjusted towards r0.

float r0=1;
float maxr=4;

//bifurcaton
for (float r=r0; r<maxr; r=r+.001){
 n=r*n*(1-n);
 println(+ r + " = r =" + " n =" + n );
 point((r*width/10),((height/2)-(height/5)*n));

}
//intervals
// the even values (1,2,3,4)
for (int i=0; i<maxr+1; i++){
 println("legende" + "=  " + i);
 stroke(100);
 line((width/10)*i,height/2+10,(width/10)*i,height/2-10);
}
// the uneven values (.5 ... 3.5)
for (float i=0.5; i<maxr; i=i+1){
 println("legende" + "=  " + i);
 stroke(100);
 line((width/10)*i,height/2+2,(width/10)*i,height/2-2);
}
-------------------------

here's the question: if you set the r0 value from 1 to 3 you will see a slice of the entire bifurcation diagram. now, how can i make this slice stretch over the same window space the entire curve used to cover (this would demand more density also, right?)? this would be some sort of zoom-in effect, where more detail is revealed from a special area.

thank you for your help
